| PATENT CLAIMS |
- Polyepoxide - Linear urethane linked polymer moieties Said adhesive material being adapted upon heating to form a cured three dimensional polymeric adhesive having crosslinks between the N atoms of the urethane linked polymer moieties, said cross-links comprising a Ph contg epoxide polymer linked to the N atoms of the urethane polymer moieties by -CH2-CHOH- linkages, with the -CH2- groups of said linkages being bound directly to said N atoms Wherein said heat curable adhesive contains 50-90% of urethane linked polymer moieties & 50-10% of polyepoxide, wherein each moiety comprises a high MW hydroxy terminated polyester joined in urethane linkage by an organic polyisocyanate |
